I have LG G6 with Android 7.0 I used to play the game for about a month, logging in with the google account. Today I'm logging in to get daily bonuses/PF prizes e.t.c. The game for some reason starts to re-download game data prompting me to connect to WiFi (I thought it's version update or something). After it re-downloads everything, it logs in, I read all the mails, get all the PF prizes, open the daily relic, press the "back" button... And black screen. Nothing happens, so I close the application and relaunch it. Now I'm permanently stuck at error 204 (An error occurred while attempting to login) while syncing game data. Both on WiFi and on mobile connection. Internet on the phone is otherwise working. Tried to reboot the phone to no avail. Game version shows as 1.4.2. EDIT: I have an old Nexus 5 with android 7.1.2 (technically not supported) that I managed to install SG onto via adb shenanigans. The same thing happens - initial data download, then I can use the game menu, enter the relics menu and try to open a relic. At which point everything blacks out, and I can't login anymore.
